VAPOR-BURNER- Specification of Letters Patent.

Patented July 23, 19.18.

Application filed February 16, 1918. Serial No. 217,645.

To all whom it may concern:

Be it known that I, EDWIN G. MUMMERY, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented oer tain new and useful Improvements in Va- -ponBurners, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to vapor burners designed for use in the combustion of hydrocarbon liquid fuels and more particularly designed for use with the less volatile fuels, such as kerosene. The invention has particular reference, first, to the means employed for controlling the distribution of the vapor around the burner tube; second, to the construction of the lighter and third, to various novel features of constructions as hereinafter set forth.

In the? drawings:

Fi ure 1 is a perspective view of the burner s owing the inner casing and lighter removed;

Fig. 2 is a vertical central section through the burner with the parts in operative position.

My improved burner is of that type in which the liquid fuel is introduced into a base rin which is in communication with an upward y -extending annular burner tube having foraminous walls. When the burner is in operation the heat which is "conducted to the use ring is suflicient to vaporize the fuel which, passing upward between the foraminous walls,-will be commin led with air so as to burn at the top with a b ue flame.

It is necessary, however, to provide means for first lighting the burner, and Where relatively non-volatile fuels, such as kerosene, are used lighting is difficult. I haveovercome this difficulty by connecting to one of the foraminous walls, and preferably the inner one, an annularlighter member having a wick or other absorbent material which Will be saturated with the liquid fuel. Provision is also made for lifting this wall to clear 1; ,other wall so that the wick may be easily lighted. In detail, A is the base ring, preferably formed of pressed sheet-metal and having its inner side B extended upuard, with perforations (l in this extension. This perforated extension forms a ortion of the inner wall of the burner tu e, the complementary portion of which is formed by an attachable foraminous tube D noras asbestos.

lnally resting upon the wall B. E is the outer wall. of the burner tube which is also foran'iinous. The base ring A is of greater width than the burner tube and its outer wall F is of greater diameter than the foraminous. tube E. G is a cap for closing the space between the walls F and E and for supporting the latter out of contact with the. liquid in the ring A. As shown this cap 9 is formed with the downwardly-extcnding outer flange II which closely lite. tmtsidc of the Wall F, and the cap is also provided. with a downwardly-extending inward flange )1 terminating in an lIlWlll'dly-flfiltllilillg' ledge J upon which the tube E rests. Thus the ring F, together with 'the cap G will form a vapor channel surrounding the base of the burner tube and forming a free passage for distributing the vapor theroai'omul so as to produce a uniform quantity of vapor in all portions of the tube.

As has been stated, the inner wall I) of the tube rests upon the upward extension C of the base ring A. K is a lighter member in the form of a ring, which holds :1. wick L, preferably of n noncombustible type, such The ring is provided with a plurality of upwurdiy-extending arms M having at their upper ends inwardly-extend ing hooks N adapted to engage perforations in the Wall I). This will form a detachable connection between the burner and the wall D, such that by lifting the wall D the burner will also be lifted. At the upper end of the wall D is a lifting handle 0, preferably formed of wire and having its ends extended at P to form a centering guide for the wall D in relation to the outer wall E. Similar guides P" are arranged transversely of the uides P so that together these guides will old the two wall accurately centered. Q is the outer imper orate wall of the burner surrounding the foraminous tube E.

In operation, whenever the liquid fuel is introduced into the base ring A through suitable valve-controlled connecting conduit, such as indicated at R, the liquid will be distributed around the ring and a portion will be absorbed by the wick L. To light the burner the inner wall Bis lifted by means of the handle 0 and the burner K is also drawn upward to permit of lightin the wick. The wall D is then re laced, whic will lower the lighter into the ase ring and will initiate the generation of the vapor. as soon as sufliclent heat is imparted to the base ring to vaporize the oil the flame of the li hter will be extinguished and the vapor wll rise in the tube to burn with a blue flame therein and at the top thereof.

lt will be noted that the downturned portion l of the cap (1 restricts the connection between the outer portion of the base ring and the port ion thereof which is in alinement with the burner tube. This will permit the distribution of the vapor uniformly around the tube, liavin equal quantities in all portions thereof an. thereby insuring a uniform flame.

What I claim as my invention is:

1. A vapor burner, comprising a base-ring having an upward foraminous extension, a detachable foraminous wall complementary to said upward extension, at cooperating foraminous wall rising from said base-ring to form an annular burner tube, and a lighter depending from said complementary foraminous wall. normally arranged in said base-ring and adapted to be lifted with the we l to which it is attached.

2. A vapor burner, comprising a base-ring having its inner wall extended upward and foraminous, a detachable forammous wall complementary to said upward extension, an

outer foraminous wall surrounding said in uer wall and spaced therefrom, an annular lighter normally ar anged in said base-ring. and hangers connecting said lighter to said complementary inner wall, for the purpose described.

3. A, vapor burner, comprising a base ring having its inner wall provided with a forannnous upward extension. a detachable fm'an'iinous wall forming a eompl meutar portion of said inner wall, a cotiperating outer foraminous wall of greater diameter extending upward from said base. a lifting handle at the upper end of said inner wall. and a lighter ring in said base'ring having hangers for connecting the same with the complementary portion of said inner \\':\ll. whereby in the lifting of said inner wall the lighter is also lifted.

4. In a vapor burner, the combination with a base ring and inner and outer io- Copies of 1:111!

raminous walls rising therefrom forming a burner tube, one of said walls being upwardly detachable from the burner, of a lighter normally arranged lll said ring, the detachable wall being connected to said lighter and forming a means for lifting the same.

5. In a vapor burner, the combination with a base ring and inner and outer foraminous walls rising therefrom forming a burner tube, one of said walls being up- \vardly detachable from the burner, of a lighter normally arranged in said ring, the removable wal being connected to said lighter and forming a means for lifting the same, and a handle member secured to said detachable wall.

6. In a vapor burner, the combination with a base ring and inner and outer foraminous walls rising therefrom forming a. burner tube, one of said walls being upwardly detachable from the burner, of a lighter normally arranged in said ring, the removable wall being connected to said lighter and forming a means for lifting the same. and means carried by'one of said walls engageable with the other to guide the detachable member and center the same.

7. In a vapor burner, the combination with a base ring and inner and outer walls rising therefrom forming a burner tube one of said walls being upwardly detachable from the burner. the removable wall being connected to said lighter and forming a means for lifting the same. and a handle for the detachable wall having portions engngeable between the walls to relatively cent r aid walls. 1

H. A i-apor burner, comprising a base ring having an upward extension, a detachable l'oramiinnls wall romplenIentary to said upward extension. n roiiperating' foran'iiuous vall rising from said base ring to form an annular burner tube. and a lighter detachil)l\' connected to the complemen ary foraininous wall to he lifted therewith and normally arranged in said base ring.
